61902 Bearing Product Overview & Core Advantages
The 61902 is a metric single row deep groove ball bearing engineered for precision radial load applications. Characterized by its compact design with a 7mm width, it offers an excellent solution for space-constrained assemblies. Manufactured to a P6 tolerance class, this bearing delivers high running accuracy and is ideal for applications demanding high rotational precision and reliability. Its open design allows for versatile lubrication options to suit specific operational needs.
61902 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Significance |
|---|---|---|
| 61902 | Basic Model Number | Denotes a single row deep groove ball bearing with a 15mm bore, 28mm OD, and 7mm width. |
| (No Suffix) | Open, P6 Tolerance, CN Clearance | The absence of suffixes indicates an open seal type, standard P6 tolerance class for high precision, and CN radial internal clearance for general applications. |
61902 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The single row deep groove construction, combined with a P6 tolerance class and tight dimensional tolerances, ensures high running accuracy and system rigidity, minimizing vibration and noise.
- Radial Load Capacity: Optimized for handling significant radial loads (dynamic: 980 lbf, static: 504 lbf), making it a robust choice for various mechanical drives.
- High-Speed Capability: The standard CN radial internal clearance and the use of a lightweight, durable stainless steel cage contribute to stable performance at high rotational speeds, with a limiting speed of 34,000 rpm.
- Material Durability: Components made from chrome steel (rings and balls) offer high wear resistance and fatigue life, while the stainless steel cage provides excellent corrosion resistance and cage integrity.
- Versatile Lubrication: The open seal type allows for the application of various lubricants, enabling customization for specific speed, temperature, and lifetime requirements.
61902 Bearing Typical Application Areas
- Precision Electric Motors and Spindles
- Office Automation Equipment (e.g., Printers, Scanners)
- Small Gearboxes and Drive Mechanisms
- Medical and Dental Instrumentation
- Robotics and Precision Positioning Systems
